Rare
Under 5% of wildlife watchers report a Black Poplar Pigmy sighting in Kyiv on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 655th most-seen of the 753 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Black Poplar Pigmy in Kyiv on a given day, against under 5% in October to June, the lowest months.
Yes
Of the 2 cities where we can rate Black Poplar Pigmy sightings, Kyiv has the highest daily chance: under 5%. Next come London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Black Poplar Pigmy is recorded against all the insects logged in Kyiv (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
